Understanding the Effect of Austempering Temperature on the Crystallographic Features and Mechanical Properties of Low-Carbon Bainitic Steel

open access: yesCrystals
The effect of austempering temperature on crystallographic features and mechanical properties is investigated in low-carbon bainitic steel, focusing on the relationship between microstructure and mechanical properties. After isothermal holding at, above,

Phase structure dependence of magnetic behaviour in iron oxide nanorods

open access: yes, 2020
Magnetic properties in iron oxide nanorods, which have many applications in biomedicine, catalysts, and magnetic resonance imaging, depend on their manufacturing processes and phase structures. Although various structures on iron oxide have been reported,

Local phase structure of wave dislocation lines: twist and twirl

open access: yes, 2004
Generic wave dislocations (phase singularities, optical vortices) in three dimensions have anisotropic local structure, which is analysed, with emphasis on the twist of surfaces of equal phase along the singular line, and the rotation of the local ...

Turbulent bubbly flow in pipe under gravity and microgravity conditions [PDF]

open access: yes, 2012
Experiments on vertical turbulent flow with millimetric bubbles, under three gravity conditions, upward, downward and microgravity flows (1g, -1g and 0g), have been performed to understand the influence of gravity upon the flow structure and the phase ...

Phase transitions with structured sparsity

open access: yesDigital Signal Processing
In the field of signal processing, phase transition phenomena have recently attracted great attention. Donoho's work established the signal recovery threshold using indicators such as restricted isotropy (RIP) and incoherence and proved that phase transition phenomena occur in compressed sampling.

Near-Atomic Resolution Structure Determination in Over-Focus with Volta Phase Plate by Cs-Corrected Cryo-EM

open access: yes, 2017
Volta phase plate (VPP) is a recently developed transmission electron microscope (TEM) apparatus that can significantly enhance the image contrast of biological samples in cryoelectron microscopy, and therefore provide the possibility to solve structures

On the structure of covariant phase observables [PDF]

open access: yesJournal of Mathematical Physics, 2002
We study the mathematical structure of covariant phase observables. Such observables can alternatively be expressed as phase matrices, as sequences of unit vectors, as sequences of phase states, or as equivalence classes of covariant trace-preserving operations.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Crystal structure of the high-pressure phase of the oxonitridosilicate chloride Ce4[Si4O3 + xN7 − x]Cl1 − xOx, x≃0.2 [PDF]

open access: yes, 2006
The structural compression mechanism of Ce4[Si4O3 + xN7 − x]Cl1 − xOx, x≃ 0.2, was investigated by in situ single-crystal synchrotron X-ray diffraction at pressures of 3.0, 8.5 and 8.6 GPa using the diamond–anvil cell technique.
